Routine Maintenance
8.1 Inspection & Cleaning

8.1.1 General Notes

In general as a routine maintenance, please make sure that the sensors and measuring
chambers are clean. Please follow the planned maintenance program in Figure 8-1. We
recommend a visual inspection every week.
If the sensor measurement is static, seems unrealistic, or the response time is slow, cleaning
of sensor and measuring chamber could be necessary
Another important routine maintenance is the validation of the sensors. Please follow the
planned maintenance program in Figure 8-1.
The strainer must be inspected and cleaned. We recommend checking the strainer every
week or more frequently. Make sure to integrate strainer check in the routine maintenance
schedule according to achieved experience during operation.
8.1.2 WM
PAH
When inspecting the G6110/G6111 PAH chamber or G6110 bushing, it is important to
check internal surfaces to verify that these are clean. Furthermore, pay close attention to
the lenses which should be totally clean from oil and salt deposits. In order to clean and
flush away solids manually, please attach the syringe to the CAL. INPUT of VALVE 4 and
use the syringe to suck out any remaining water inside the measuring chamber. Clean
chamber surfaces with a clean rag, pour clean water inside the chamber and suck out the
water again – repeat this procedure until water and the rags appears clean.
TURBIDITY
The Turbidity Module is equipped with a wiper unit that effectively removes fouling from
the optical parts. The flow through the chamber removes most solids and keeps them from
settling. In order to clean and flush away solids manually, please turn VALVE 2 to DRAIN,
then remove the wiper unit and pour clean water into the measuring chamber.
PH/TEMPERATURE
The pH electrode is kept cleaned by the flow of water. In order to clean and flush away
solids manually, please turn VALVE 1 to DRAIN, then remove the pH/temperature sensor
and pour clean water into the measuring chamber. Cleaning of the electrode is done using
clean water until the glass tip of the electrode is free from fouling while ensuring that the
tip of the electrode remains moist during the whole operation.
Be careful not to damage the glass tip of the electrode by mechanic impact.
